I have one I keep around for accuracy testing when I’m working up a new loads. Mine has been rock solid in the past. The bolt is easily removed with the mount in place. The only issue I have with it is the scope is mounted quite high over the rifle and a cheek rest of some type is needed for proper eye alignment. As for a scope it depends what your after. If your going for a Sniper clone look for one of the older 4 power scopes like a K4. I end up using what ever I have laying around and remove it when I’m done.
